OK. I'M GOING NUTZ ! Sorry for the drama• I re-mixed the 600. Distilled water. No sign of white. Prior to this batch I washed the interior of the fridge with vinegar . Thoroughly dried and left open to air for 6 or so hours • still no mold growth. Did the vinegar dry but remain? Thus Killing my mold?

Paul, thank you. for your advice. This is my third batch. first was excellent. Second bland but I deeply suspect I missed an ingredient : this batch looks and smells great. Doing 2 ways: one in pork middles in the drying chamber. One batch in Umai dry bags in the fridge . Both same recipe. we'll see.
